P0441 code and gas pump keeps stopping when filling up

I have a 98' audi a4 2.8 quattro and recently got a po441 code when driving on the highway. I've also noticed that when I go to fill up the car the pump keeps stopping every 2 seconds making filling up the tank a challenge and developing a technique to avoid it. Why is there a pressure build up in the tank is the code related? I've read on the other posts that it could be the purge valve?

Any help is greatly appreciated here is the code off the vag-com

16825 - EVAP Emission Control Sys: Incorrect Flow

P0441 - 35-10 - - - Intermittent

Just replaced the purge valve bought it through some auto parts website, it says bosch on the purge valve but also says made in China, we'll see how the car fills up next tank it figures i get it the day after i filled my tank. Check engine light is off for now, but the abs light is on now! Read the codes and looks like i'll need a abs wheel speed sensor

The purge valve (N80) will most likely solve the EVAP Emission Control Sys: Incorrect Flow fault code, as they are a common failure item when they get old.

The filling problem is probably something else... a vent problem in the tank.

Bentley has a VHS tape Self Study Program that explains the EVAP operation and shows what happens when the fuel tank is being filled.

email them to see if they have a digital version that they would be able to make available for downloading.

Found a VW EVAP PDF that should still apply to your system... have a read to give you an idea of what the problem might be.

PDF is attached.

Sounds like a breather valve problem to me.
